This is a note to let you know that I've just added the patch titled crypto: rsa-pkcs1pad - Use akcipher_request_complete to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-rsa-pkcs1pad-use-akcipher_request_complete.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit bccd0b929fb80742ce25db366f3b0695917c78f7 Author: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> Date: Tue Jan 31 16:02:04 2023 +0800 crypto: rsa-pkcs1pad - Use akcipher_request_complete [ Upstream commit 564cabc0ca0bdfa8f0fc1ae74b24d0a7554522c5 ] Use the akcipher_request_complete helper instead of calling the completion function directly. In fact the previous code was buggy in that EINPROGRESS was never passed back to the original caller.
